Memory segment emulation model for virtual machine

摘要

A method of emulating segment addressing by a processor that includes initiating a Virtual Machine Monitor in a kernel mode; initiating a Virtual Machine in a user mode; forming a dynamically mapped table in Virtual Machine Monitor space, the dynamically mapped table corresponding to a table of segment descriptors of the Virtual Machine; populating the dynamically mapped table with descriptors that raise exceptions upon an attempt by the Virtual Machine to address a corresponding segment; and mapping a descriptor to the dynamically mapped table upon the Virtual Machine's use of that descriptor.
